The internal energy of a system may be changed either by allowing the exchange of heat with the surroundings or by doing work on the system. If the reaction is carried out at a constant volume, pressure-volume work done is zero. We know that qp = qv + ngRT. Internal energy is an extensive property and a state function. The questions from (i) to (iv) consist of an assertion (A) and reason (R). Choose the correct option:
Assertion: Internal energy of a system is an extensive property.
Reason: The internal energy of a system depends upon the physical state and amount of the substance.
- a)A and R both are correct and R is the correct explanation of A.
- b)A and R both are correct but R is not the correct explanation of A.
- c)A is true but R is false.
- d)A is false but R is true.
Correct answer is option 'A'. Can you explain this answer?

As internal energy is U = mcvdT so it depends upon mass m, and specific heat cv, i.e., it depends upon amount and state of the substance.

So Internal energy is an extensive property of system.
For example if we take a container filled with gas and partition it into two halves, mass in each side also get halved, thus internal energy U = mcvdT is also reduced to half.

Assertion and Reasoning Explanation:
Assertion: Internal energy of a system is an extensive property.
Reason: The internal energy of a system depends upon the physical state and amount of the substance.
Explanation:
- Internal energy as an extensive property: Internal energy is an extensive property because it depends on the amount of substance present in the system. The internal energy of a larger system will be greater than that of a smaller system, assuming all other conditions remain the same.
- Physical state and amount of substance: The internal energy of a system is influenced by the physical state of the substance (solid, liquid, gas) and the amount of substance present. For example, the internal energy of a system containing a larger amount of gas molecules will be higher compared to a system with fewer gas molecules, assuming the same conditions.
Therefore, the assertion that internal energy is an extensive property is correct because it varies with the amount of substance in the system. The reason provided also supports this assertion by highlighting the dependence of internal energy on the physical state and amount of the substance. Hence, option 'A' is the correct choice as both the assertion and reason are correct, and the reason correctly explains the assertion.
